Description

General description

Tröger base (TB) is a chiral heterocyclic amine with chirality due to the presence of two stereogenic nitrogen atoms.[1]

Application

It was used as an standard analyte for testing the enantioseparation capability of the chiral stationary phase column; in a study to understand the covalently bonded cellulose tris(3,5-dimethylphenylcarbamate) on a silica monolithic capillary column.[2]

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
